The'schedulo referred. to in these Letters Patent and making part of the same.

To all whom it my concern:

Be -it known that I, DAVID SLAUGHTER, of West Hempfeld township, in the county of Lancaster, and

`State of Pennsylvania, have invented new and useful Improvements on Cultivators; andil do hereby declare that the following is a full description of the cou-. struction and operation `of the same, reference being had to the accompanying drawings, making a part of this specification, iu"which Figure 1 is a perspective 'view of the improvements in place. -Y a v VFigure 2, a top view, showing'the side beams closed.

Figure '3, the same, withthe side wings drawn out.

Figure 4,'a side view or elevation. i

Figure 5, the central shovel, Vwith its wings and appliances.

Figure 6,- one of the live ordinary shovels.

The nature of my invention consists in providing a means to expand and 'contract the side arms ofthe cultivator and the-rear central shovel simultaneously, by means of a turning-shaft, for the purpose of regnlating its operation to thewidth between' the rows, whether regular or irregular, and-while in'mot'ion, to adjust without stopping.

To enable others skilled in the art to make and use my invention, I will morefully describe the 'several parte. y

There is a central beam', A, and two side or wingbeams, B Bf, as shown, in numerous cultivators.

The side 'beams are, however, supported 'between two triangular plates, or pieces, D D', the base `extending on eachside ofthe central beam, so as to form an open box or bearing for the side beams, in which they tluru on a pivot-bolt'in front.`

The handles H are fastened to the top of the upper triangular plate D, and braced together by a crossplate, E, which alsofforms the upper bearing for a vertical turn-shaft, C, with radiating arms, which shaft has its step or lwer bearing in the central beam, A, being also provided with apiniou, which meshes into a pair of curved and cogged racks, K K', ou opposite sides.

The outer end of each rack is secured to its respective beam, B B, there being a loop, L, on the inner end o f each, so that the other rack slides freely in said loop of its counterpart, as shown, with the pinion. on

' while holding the handles, arel easily operated, and,

by aiiixing-any ordinary springcatch,'the arms can be temporarily locked to hold the adjusted beams in place for thetime being, and readily unlock, to change the same, as the nature of the case demands.

u I am .aware that'hinged sidebeams are common, y and made adjustable by various4 combinations; but I am not aware. of any arrangement for that purpose, substantially, made oroperated, as is fully shown, and herein set for/th,

- Fig. 5. illustrates the central shovel Q Q, with a cen' tral supporting-brace, R R.

t The sidewings are provided withjan ear, and hookedz projection, r, enteringl through an enlarged opening iu the connecting-band P, which latter is-fastened by a pin, p, to the end of spectively. y

Thereis also a guide o1' stay-brace, Z, shown fastened on the lower side of the beam A, from the tcp of whichalso rise the handle-supports Gr' G.

.This description, in connection with the drawings, will sulce to convey a correct idea of the construction and operation of my improvement.

What I claim asmy invention, and desire to secure by'Letters Patent, is-

The construction ofthe central shovel or scraper Q with its side wings B R, hook-ends fr, in combination with the connecting-straps P, the side beams B B', together with the wing-stay or guide Z, arranged and operating substantially in the manner 'and for the purpose set forth. v
